EDWIN BORDEN, OF FALL RIVER, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO JOHN vISI. PITMAN, OF SAME PLAGE.

MILK-WAGON.

SPECIFICATION forming part of Letters Patent No. 270,539, dated January 9, lesa.

Application tiled September 26, 1882.

To all whom it may concern c Be it known that I, EDWIN BoRDEN, of Fall River, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Milk-Wagons; and I hereby declare that the f'ollowing is a full, clear, and exact description of the same, reference being had tothe accompanyingdrawings, forming part of this specification.

This invention has reference to an improvement in wagons orother vehicles for transporting' milk; and it consists in the peculiar and novel construction and arrangement by which the milk is protected against the effect of the -temperature or change in temperature by snrrounding the can with v a box constructed to form a poor conductor of heat.

The invention further consists in the peculiar and novel constructionofthe box by which the removal of the can or cans is facilitated', and it furtherconsists in the peculiar construction by which the air in the box and the milk can be kept at a uniform temperature, all of which will be more fully set forth hereinafter.

Figure l is a perspective view of the body of a milk-Wagon. Fig. 2 is a vertical sectional view of the saine. Fig. 3 is a horizontal seotional view of the milk-wagon.

In the drawings, A is the can or receptacle for the milk. It is preferably made square, and only one can is shown, ofsuch size as to nearly fill the body of the box; but two or more cans or receptacles may be used and placed side by side, and, in place ofthe square can or receptacle, cans circular or oval in their horizontal cross-section may be used without altering the nature or eli'ect of the invention.

a is the opening through which the milk is placed into the can, and b is a valve or faucet for controlling the discharge of the milk, each receptacle being provided with an opening, a, and a valve or faucet, b.

B B are the top, bottom, and sides ot' the wagon body or box. They are made of two thicknesses, so as to form a space between the outer and inner portion ofthe box,whieh space is filled with any suitable non-conducting material, so as to prevent the conduction of heat or cold` through the same, and thereby prevent (No model.)

the freezing of the milk in winter and the heating ot' the same in summer during the transportation.

The can or cans take up only a portion of the interiory of the box, one end being partitioned off, so as to form the receptacle O, into which ice may be placed in summer to maintain a low temperature Within the box, and cans filled with hot water in winter to maintain sufficient warmth and prevent the freezing ot' the milk. Air-spaces D D are left between the can A, the receptacle C, and the interior of the box B, so that the air can freely circulate, as is indicated by the arrows in Fig. 2, and a uniform temperature maintained. p

To facilitate the removal of the can or cans,` the end E of the box B is constructed to slide vertically upward, the end being provided with tongues sliding in vertical grooves formed in the sides, the lower edges ofthe double slide E being provided with openings, through which the pipe connecting the valve'or faucet b with thecan or cans passes, and to protect the faucet b against injury the hinged box F is placed over the same, so that it can be readily swung aside and the milk drawn from the can.

H is a double door, placed in the top of the box B to give access to the inlet a of the can A for filling the same.

' I is a seat for the driver ot' themilk-wagon, and K the foot-board.

The whole is mounted on the ordinary running-gear ofa wagon, and is usually supported on springs. Milk may be taken from the dairyfarm to the town or city and retailed to consumers without injuryto the milk in thecoldest'winter or hottest summer weather, and thus pure fresh milk, not liable to turn sour, may be secured.

Under the receptacleOaspace,D, is formed, to which access is had by means ofthe door L in the front end of the box, and into this space smaller cans of milk or cream, or other articles which are to be protected against heat or cold, can be placed, and be readily removed when required.

lnstead of mounting the whole on the runring-gear of a wagon the box may be made without tbe seat I and foot-board K, and may structed to prevent the transmission of heat ICL thus be transported in railroad-cars, and at the proper place be slid onto the platform of an ordinary wagon, and to facilitate such removal the box B may be provided with small wheels or rollers. In either case, Whether mounted on a running-gear so as to pass between the dairy and the consumer directly orto be shipped by rail and then placed on a Wagon, the box constructed as described will protect the milk iu the can or cansagainst 'the excessive cold of winter and the heat of summer, and thus prevent the spoiling of the milk.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the box B, conor cold, of the can A, provided with t-hefaucet l), the double end E ofthe box B, constructed to slide vertically, and the door H, constructed to transport milk and protect the same, as described.

2. rlhe combination, with the box B and can A, ofthe receptacle C, constructed to contain ice, and the comlnuuicatingair-spaeesD D, arranged to facilitate the circulation ot' the air, as described.

3. rlhe combination, with the can A, ofthe box B, constructed substantially as described, the receptacle C, the receptacle D, the doors H and L, and the hinged box F, constructed to protect dairy products during transporta-- tion, as described.

4. The combination, in a milk-wagon, with the boxB, provided with the door H, ofthe slide E, the can A, and an ice-receptacle,tl1e whole constructed substantially as described, to protect the mill; during transportation, as described.
